1 of the Campaign : Improvement of Children's Immunisation Coverage : Only the branches for infants, children and adolescents in the public health departements carry out regular data collections concerning the protection given by vaccination of children and adolescents.

These immunisation records as well as selected studies show a lack of vaccination and immunisation in these age groups.

The analysis of these immunisation records by the public health departements shows specific vaccination deficits which are basic for specific strategies that must be taken to improve the immunisation coverage.

The main objective of the branches for infants, children and adolescents in the public health departements is to make these data available for all persons who are regionally responsible for children.

All these persons together have to develop strategies to improve the immunisation coverage in the short as well as in the long run.

The public health department coordinate these strategies, validate coverage data and and evaluate them.
